Euro 6d and Euro 7 emission standards

Euro 6d euro 7

European Euro 6d emissions standards, also known as Euro 6d full or Euro 6.3, were introduced in 2021. Euro 7 standards will apply from 2025.

The Euro standards represent the maximum limits of polluting emissions that cars must not exceed and are set by the European Union. Limits are lowered regularly. The European Commission (EC) is preparing the next stage of approval requirements for vehicle emissions, which will be known as Euro 7/VII.

Euro standards for vehicle emissions were first introduced in 1991 with „Euro 1” for passenger cars (symbolized by Arabic numerals) and in 1992 by „Euro I” for commercial vehicles (symbolized by Roman numerals).

Date when the emission standards were introduced:

  • Euro 1: January 1991
  • Euro 2: January 1997
  • Euro 3: January 2001
  • Euro 4: January 2006
  • Euro 5: January 2011
  • Euro 6: September 2015
  • Euro 6d-TEMP (Euro 6.2): September 2019
  • Euro 6d (Euro 6.3): January 2021

All new mass-produced vehicles sold from September 2015 must meet the emission levels of the Euro 6/VI standard.

Euro 6d

The Euro 6.d standards will impose a threshold of 85.8 mg/km NOx on petrol cars, and below 114.4 mg/km NOx on diesel ones.

Euro 6d-TEMP and Euro 6.d are the standards for RDE measurements. They have the same level of emissions.

The WLTP procedures were continued by measuring emissions in real traffic conditions RDE (Real Driving Emission), which certifies that the vehicles produce low emissions (NOx and PN – particle number) compared to laboratory tests.

Euro standards set emission thresholds for polluting gases: NOx (nitrogen oxide), CO (carbon monoxide), fine particles (PM) and unburned hydrocarbons (THC and NMHC).
